V8 Freak, can you tell me who did your map please. I have a similar set up to you but Im getting MAF issues. I would like to get it sorted with no boost box a higher bar map sensor and upgraded MAF

Hello there, I have been reading this thread and I have the same problem but its worse. The rangie is a 95 4.6 with lpg it will run for a short while and then stops miss firing and has problems re starting. Again the same on petrol and lpg - slightly better on lpg. The question I have is the spark plugs - one of the posts say use normal ngk plugs but no one said anything about not using the more expensive platinum tip ones. Also if H-M3 is reading this. what cured the problem ??
